Actually, a second film slr probably costs less than a mid range digital PnS nowadays.
Long ago, during the days of film, I bought a Dynax 700si (probably around a D300D700 in terms of level today) for only S$700.00. That was an AF SLR with all the geebangz.
A pure manual slr like the FM2 or the like will probably only cost you S$200-300. You can check out a bit more on these as I haven't looked at film slr prices for many years.
Also, you can even find a second hand DSLR like the D100 or S1pro/S2pro for a couple of hundred dollars.
