Semi-OT? HP 1630G Logic Analyser (grabbers, invasm packs & disk drives)

Hey folks; So I'm busy reading the manual to my brand-new-offa-eBay 1630G and, page by page, I'm more and more impressed. I've never owned one before and it just seems like pure magic. I've got it hooked up to a huffy Vector Graphic in my basement (which diagnosed a bad Z80 in a matter of seconds on my test try!) and boy is it useful. First business - does anyone have swaths of the double-grip HP probe grabbers they might be willing to part with for a reasonable sum? Just askin' :) I'm reading the section on the 'inverse assembler', which really is remarkable (like I said, I'm new to this) to have it disassemble various CPU instruction sets. What I do not have, though, is either the appropriate disk drive set (HP 9121S or 9121D, according to the manual) nor any of the invasm packs. I don't suppose there's anyone out there who may be willing to also part with either of the above, again, for reasonable recompense? With the Vector I'm interested in Z80 invasms - but, frankly, the options seem endless given the smattering of 8-bit processors I have covering my shelves in need of attention. There's a 9121D on eBay (6 days out) for $60 w/shipping, which is... do-able but seems a shade hefty. Maybe they're getting harder to find these days, I don't know. As for the invasm packs, for all I know they're complete unobtanium - but I figured I'd go to the repository for such knowledge and see what people thought. Many, many thanks to all. - JP
