As pointed out you can get the wanhao I3 from a UK supplier for less than £300 – doubt if the Aldi clone is significantly better or worse than the UK supplied version but the UK supplier is a specialist 3d printer outlet that offers support.
What I do know is the i3 is a very competent printer out of the box and without much finessing. cant say if it is as good as £900 printers but I bet there are some high cost printers that are not as good as the i3. I would suggest it is slightly stiffer than a Prusa, but not by much. Y axis can be improved though.
I used mine to produce some very serviceable MXL timing gears to drive a mini wood lathe (the picador pup no less!) and a bunch of 20 DP gears for the M7 (well not actually for the M7 but for an EW to replace the absurd DP16 set that came with the EW). Plus a whole bunch of other bits an pieces, mainly PLA. The supplied bed/print head will get hot enough for ABS, but not nylon
Not perfect by any means and all modestly priced 3d printers suffer the old engineering bugbear of a lack of rigidity, but this can be addressed if required, also in the case of the i3, the stated print height was a slight exaggeration more like 170mm than 200..
However, I was well pleased with it so far and you can use it 1/2 and hour after unpacking.
If new to this recommend you do your research etc
