Logic Analyzer Recommendations

Hi All, My current logic analyzers (an HP 64000 system and a Dolch LAM4850) have been forced into early retirement and I'm looking for a replacement. I need around 100 channels, not terribly fast (100-250 MHz -- faster is ok too, obviously) and it might be handy to have the ability to plug in a scope card and/or a pattern generator. I've used the HP 16500 quite a bit (in a past life) but I have not had much experience with other machines (Tektronix TLA7xx, HP 167x etc). There seems to be a lot of 16500 mainframes and cards available -- but they are getting old and they are pretty BIG. OK, so an HP 64000 ain't exactly petite either so maybe size doesn't matter THAT much... Anyhow, I'm looking for recommendations. Something that will give a few years of service, and cost less than $4000 (or thereabouts). I have to keep these poor old computers running somehow -- plus a few new developments from time to time. Advice would be appreciated, Pat
