Erin,
This seems like a guess/scale focus camera... just something to keep in mind.
How much are you looking to spend on it? Take a look at ritzcam.com for some inexpensive 120 alternatives. I recall them having a Zeiss Ikoflex TLR for 60 bucks, and a few Agfa folders around 15 (I bought a Isolette V for 12, and a Speedex B2 for 20 - both scale focus). For an entry into medium format, I'd recommend a TLR or anything with focusing.
Also, check Keh.com as they had a Ciroflex TLR for about 40 bucks last time I checked.
good luck from a fellow college student,
André
