I guess by mentioning using a spreadsheet above I might have been implying buy the cheapest, far from it.

It is a good idea to do a spreadsheet, Keith.
I have seen some suggest that you should treat buying a Mill or Lathe etc as an item that you will write off after a number of years, I seem to remember 5 being suggested. But being a Yorkshire man I like to get my monies worth out of things. That is the bit that is really hard to determine, how long will spares be available.
Keith
That is a good point Keith.
The 5 years suggestion is mainly based on the user. So how long is a piece of string: factors: light use/heavy use/outgrowing original needs/ability.
Regarding spares, there are various observations to be made here:
1. We started selling SIEG machines around 2004. From then until now, we have carried a good range of spares for their machines, be they for machines which we have discontinued, or current, or some other SIEG machines which we don’t sell, but for which the parts are the same. These can be found in machine spares section on our site: LINK . However, we do not sell all parts for all SIEG machines.
2. We only sell SIEG machines. We do not change from one machine manufacturer to another, so the spares we sell will fit SIEG models as specified. Some of our competitors will change factories based on price or relationship with SIEG or new factories, especially for products they think are generic (but not necessarily), for example fixed/travelling steady for mini-lathe, or certain parts for mini-mill or bigger. We don’t suggest any compatibility of spares for machines made by factories other than SIEG. SIEG spares for SIEG machines. NO electrical spares compatibility with non-SIEG made machines.
3. SIEG have plenty of distributors around the world. Their main production is for the U.S. market which has the highest consumption of SIEG machines. So spares for SIEG machines are more easily available for new and old machines. Here is a list to their distributors LINK
There are a few ‘own brand’ machines sold by companies such as Machine Mart – mini-lathe and mini-mill (but not the combo), which are also machines made by SIEG.
Generally, to the best of my knowledge, mechanical spares for SIEG made machines are available for 10 years plus after a model is discontinued by SIEG, depending on how popular the machine is. So even if a distributor stops selling a SIEG machine, I would suggest that probability of spares availability for a good period 10 years+ is high, because very few models have been discontinued by SIEG, even if a distributor has stopped selling certain models. For example: ARC has stopped selling brushed motor models of SIEG machines over time (even though some distributors still sell brushed motor models), but we still maintain a range of spares for those machines which were sold by us.
4. Electrical spares availability: Certain control boards have been discontinued by SIEG – generally around 5 to 10 years after last production of a machine fitted with such a control board. Other than an upgrade/improvement to an existing control board issue, Control boards have usually been changed to meet with new regulatory requirements, eg. lead free. For very old dead control boards, you will usually find someone on a forum somewhere who has managed to replace dead components (such as MOSFETS) on an old board. So information is available for certain obsolete boards on forums. Others have replaced obsolete boards with conversions to 3-phase motors with inverters.
