Fantastic! Thanks for all the advise... I'll let you know how everything goes...

 

Ok, Hamlet fan, forget about using JB weld or epoxy on your radiator; been there, done that, and it doesn't work (very long or reliably, anyway.) Save your pennies for the replacement rad. I'd jump on the $120 one, but make sure it holds pressure.
After that, talk us through the road test, and we can give you better advice on what the next fix may be.
Yes, it's (frankly) a bitch to not be riding on the seeming few good days we have in the Midwest, and to stretch pennies to buy parts for repairs you think about all day during work. Just wait till you get married, have a kid or two, and your Saturday and Sunday anticipated ride becomes a plumbing repair, or better yet, helping the in-laws. Learn patience now; you'll become a better spouse in a few years.
