Looking For a Film SLR

SIgh. I would like to have a proper film SLR to use for my hobby but I am not familiar with other models. Been using Nikon's FM3A during my earlier days from school and I like what I had so would like to get my hands on one set but it is not cheap. What I found on ebay are costly and the only reasonably priced one I found has some pretty weird bidding on it. Why would someone keep upping his own bid when he is the highest bidder? Sigh.....
