They aren't going out of business that's for sure since Sanwa/Aitronics systems are very popular and great bang for buck. Many people use them from novices to pros. Your best bet is to buy from Hobbypeople. They've got the best prices on Sanwa/Airtronics systems/accessories. It looks like Hobbypeople doesn't carry the MX-3FG anymore. They only carry the newer more expensive MX-3X.

It's pretty strange that they took down the old website and not reuse any of the info there to put up a online store with practically no info at all. The really sad thing is they charge you to download their user manuals.
