Replying to Digital Setup help!

So I haven't been shooting much lately, and that is mostly due to a lack of time and motivation, but I also blame it on the fact that I'm starting to agree with the people who told me that film would be more expensive in the long run than digital. So I need so help making decisions

My current setup
Olympus OM-1n black, bought from Keh in BGN condition, minimal brassing
28mm f3.5, 50mm f1.8, 135mm f3.5 all in BGN condition

Pentax ME, BGN condition, a few small nicks here and there
Random worthless Vivitar 35mm, 50mm f2, 135mm f3.5

Mamiya RZ67 Pro, Pretty good condition, I think I spent around $900 for the whole setup
wide, mid, mid-long lenses, cnat remember exactly which ones
2 backs, gossen luna pro sbc, red and orange filter, Burton pack, manfrotto 3021b pro legs, bogen 3030 head.

Voigtlander Vito CSR, decent condition, broken meter, pretty much worthless

Canon Eos Rebel 2000, fair condition, again pretty much worthless
28-80mm f3.5-5.6 II



So what should I do? I haven't set out a budget yet, but just keep in mind that I'm poor as shit right now and most of my money I earn will have to go towards school. I've been thinking of a few options and I'm looking for some more suggestions from you guys

1) Sell Everything, get a canon DSLR and lenses etc, get a older EF mount body just to have the option of film.

2) Sell everything but the RZ67 setup, get a less expensive DSLR setup, or maybe a sony Nex 5

3) Sell everything but the ME or OM-1 setup, Get a DSLR

4) ????

I know those all seem pretty vague, sorry.


I had some other random questions too:
Canon 50d vd 5d classic? Is full frame worth the older tech of the 5d? Finding a cheap wide angle for full frame would probably be cheaper than say a 11-16 or something of the like.

I don't know anything about nikon, but I don't want to count them out. What would be a camera similar to the 40d or 50d in price/value and features. Is there a cheap-ish full frame nikon dslr similar to the 5d classic out there? Is it pretty easy to get good bang for buck lenses like the canon 28-135mm for example? I like that nikon has never changed their mount and I really like vintage glass.

Oh yeah and all this is strictly photography, I don't have any interest/care for video.

Sorry this is so jumbled up, any help is greatly appreciated
