Well as far as Oracal goes you could switch to 200 lam which should save you about $0.07 a sq ft (based on my prices), and there certainly are cheaper vinyls than 3640 but i don't have any experience with them.
I sell a sweet 5 Mil Glossy with Permanent Adhesive for $0.12 a sq.ft and my house laminates are only $0.15 which would be just as good as 210 lam from Oracal
whats your email I will shoot you a price guide.
Why are you laminating for short term applications? If you're using even an eco-solvent printer, you should get at least 1 year durability outdoors unlaminated.
for my economy projects (coroplast/MDO signage), I go through 3 rolls of MacTac media to 1 roll of overlaminate.

Heck even that's pushing it, I'd bet we're 10-1...
By the way, getting to the OP's question, I recommend the General Formulations 203 gloss. Not sure how it compares to the Orajet you're using in terms of cost, but we've been using the 203 for several years now and have zero complaints.
