Baby mac,
Dane and Pete have pretty much said it all. I can really relate to your finnical situtation right now though. Try hitting you routines with completely different excerises. I love dumbell flies which really gives me a good pump. We have a Cybex machine at my gym where you can preform incline lifts and you put plates on the ends to increase the ampount of resistence that you want. This leaves the amount that you want to lift restricted only to your own physical ability.
