Dear Top-Cat,

If you really want to enlarge using traditional darkroom methods, a 4x5 enlarger can be obtained at a reasonable price. However, contact prints can be made quite easily and they can be scanned with a flatbed scanner until you are sure you want to take the plunge. If, of course, it is simply sheet film you are new to, find a large format enlarger without delay! Optically printing sheet film is immediately satisfying, particularlly if you only have experience with 35mm.
