Delivery time isn't usually too bad for me - except on orders from the US, sucks because like 90% of my orders are form the US - but customs can do one, bloody charges. I seem to think mine was decently priced and came from a guy in Malta. I think it was cheap because it is rusty, the selection wheel is a bit wonky and the power cord was busted to hell. Works though.

The RZ-1 was a good deal, bought that as parts on the chance it was the classic button problem - it was, just a slipped membrane with broken retainers, so duct tape sorted that out and I only need the sample and MIDI button as I control it from the PC, needed the pots and sockets cleaned too. The CZ-1000 I bought as damaged (No volume control - full volume only) and the Korg was bought with a flat battery (apparently broken) - I think the CZ-5000 is the only thing I ever bought as fully working, but they are pretty worthless (or were, I think I played a part in making them worth more) so I was taking advantage of people's ignorance, in that they usually hated a keyboard they had never used or even heard... Funny thing is, most people start liking them when they've used one. Of course, only the Yamaha is GM compatible out of this selection. Oh, the MT-32 was fully working and cost far too much, then broke when I tried writing music with it... bloody piece of junk. The SCC-1 was boxed and untested (and cheap, circa 2004) and the SoundCanvas modules I had were free or close too - just as well because they were horrible. My MC-303 was free too and needed to be because it was plain awful, but I sold it at the end of 2007.

Doesn't matter too much on the MU90R here as the DS-1 is good enough for PC games anyway, none of them really make use of the extended features of the MU90. In fact, even the MU50 would probably be overkill, hell, even the DS-1/724 is kinda overkill and it would probably only be worth getting a module if you planned to write your own songs... Though that does tempt me to see how impractical I can be and use multiple overpowered synths for simple GM music, just to see how many I can actually set up and use at one time. Once wrote a song which used six synths at the same time, that was a pain in the ass.
I doubt that MIDI will sound good on an AWE32, given it's an XG file and relies on extended programs and features. It will play though.
