hello everyone.
i just registered to the forums hoping that i can find help here
i have near zero knowledge about bikes (although i have a friend who regularly read biking magazines but nowadays he does not have enough time so he cant keep up with the current technologies and manufacturers), and since previously i have very low end no-name bicycles i am planning to buy one more advanced (but not professional)
currently i have an offer for a bike that is not cheap but just affordable, but i can find no information about the manufacturer.

it looks something like this:
http://images4.okr.ro/auctions.v3/70...56-700_700.jpg

same coloring except for this one has no horns on the handlebar and i think it has different equipment (only picture i found on the net while searching for "vertical xt")

on the body it says "vertical xt", it has shimano deore xt brakes and shifters
front suspension is RST, rear is DNM
it is used

i need it for a generally reliable bike for mountain biking, cross country (around 100-200 kilometer distances), city use, but nothing extreme - i am not trained and would not like to stress the bike either

any advice, or previous experience regarding this bike or the manufacturer?
i am mainly concerned abount the body itself as it seems that the accessories are all right.

thanks.
