I'v had a mini, and i can honestly say it was the most awesomestness thing i'v ever shot!
Heard its pot luck weather you get a good one or a faulty one, think mine was abit of both
doesn't work anymore...
Anyways minis are dirt cheap, round £210 new and £150 on here i do believe. but they deff ain't easy to clean if you get a chop and you have to clean out the entire bolt assembly and re-lube, would easily take 10mins which realy is too much time sometimes.
Needed very little upgrades on a mini, the standard board is great as a stock peice of kit, heard nothing but good things about the trigg from other players, i would also have to say its fantastic, but i had minor bounce probs with mine so that might take some time to fiddle around with (or i got a naff trigg which loved to bounce
).
personal opinion, get an ego! techs are always at hand and there easy to maintain with spares and plenty of support from eclipse as well as direct proucts for the ego from them.
