Yes -- I'll second Rob's post.
It's a long story which has NOTHING to do with the device, but we just found ourselves replacing our Oxycheq analyzer. I ordered the El Cheapo, thinking that I'd had fun putting together Radio Shack kits years ago. I can solder, and I can assemble.
What it turns out I didn't have the tools or the know-how to do was to cut precisely machined rectangular and round holes in very hard plastic. To my absolute drop-jawed astonishment, the box itself is not machined AT ALL. You have to orient the contents, mark the spaces, and figure out how to cut perfect openings for everything. I did not own a miniature hacksaw, which had to be purchased, as well as a tiny soldering gun AND special solder . . . and since the instructions tell me to do some things that don't match what I'm looking at at all, I'm going to have some interesting challenges ONCE I GET THE DARNED CASE DONE.
Had I had ANY idea of how totally DIY this was, I would have chucked the extra couple hundred at Oxycheq very cheerfully. Not only is my time worth something, but I've only got so much stomach lining.
