If been running a Broxa for 3 years. No problems at all with it. Decided last year to put a tighter barrel in and a new Hopup. Still no issues. For $89 I'd buy a couple and rent them out. Not a big investment and if they die, you will probably have goten your money back a couple of times over. Just make sure you dump the high cap, it is terrible.
A local airsoft site has been running about a dozen of the Broxa's for the last year, no issues there either (Except the highcaps).
You will eventually want to get a better gun, I did (TM M14), but to start off with, it will do.
Nothing says loving, like a head shot!
