If y'all haven't guessed by now, Jarvis and I are pretty much sold on the Minolta gear. I have several srT 101's, XD-11's and XE-7's as well as an SR-7 and they get used most of the time by myself or my son when we go out to shoot. The XE-7 is battery dependant and can be finicky at times (needs a CLA) but it is spot on with a fresh battery and takes fantastic pics especially with the pre-MC lenses (couldn't possibly be me).
I have the 300/4,5 MC ROKKOR lens that I picked up in a package deal. Great looking lens but it doesn't get used much as I prefer to use wide angle lenses most of the time and nothing more than a 135 for portraits. If you haven't gotten that lens yet for $70 do so if you use tele's. KEH has a 300/5,6 in E+ condition now for $89. Get it while the gettings good. Check out this review of the lens
