Thanks again guys! There's an old "tank" style Amiga mouse on eBay now that I'll keep my eye on... that is if I'm not too stupid to miss the bid like I did last night on that deal Weirdami brought to my attention. It had like a half hour left and I had to go shovel snow out of my driveway thinking I would remember to check back in 20 minutes. Well, needless to say I checked back just 2 minutes too late, and the whole lot sold for less than 17 bucks!--the video modulator I need, an external floppy drive, some misc connectors, and--get this--an entire a500 computer system with power supply that the guy stated he would not charge additional shipping on because he was adding it to the lot after the fact! Somebody got a DEAL and it was not me--I'm such an idiot for being aware of this auction and yet still missing it!
So... I'm hanging my head in shame and respectfully bowing off now. It may be awhile before I check back as I may be stuck without a video connection for awhile. Incidentally, if anyone has a spare A520 video modulator they wouldn't mind parting with, send me a PM. Thanks!
