Since my Draftsight expired I've tried Solid Edge, Qcad and TurboCad. SE has a fatal issue for me in that you can't tie linetype/colour to layer. I then found Qcad easier to use than TC, although I'm sure with perseverance I'd get used to TC. There is a free 15 day trial of TC, so you can give it a try, then it's £49, which isn't expensive. QC isn't quite free, the free version shuts down after 20 minutes or so and you have to save/re-start. I'm going to invest my £30. Just one issue, if you are sent something drawn in SE and open t in QC the text is all scrambled. What was written as 'h' in SE comes out as 'ftxtlb0lli0llc0lp34;W1.;h'. This both as dwg and dxf, and with SE fonts and regular fonts. I'm sure there is a way round this, but I'm going for QCAD as I said. Drawings created in DS and TC open up fine in Qcad, and drawings from SE open in TC and DS, so it is something about SE that QC doesn't like. I'm not going to let it worry me.
Once you're up and running with QC it is well worth investigating using keyboard commands rather than the pull down things, for instance 'CR30' will draw a 30 radius circle where you click the cursor, lv10<tab>s draws a vertical upwards line, lv10<tab>e vertical down and so on. Once you get used to it it's a lot faster
