Gassers has a Sekonic L-508 they rent for $15 per weekend or $45 per week. Rent that one for your first week and then ask around the class. Likely someone will have something to lend you. Otherwise buy a used one from Gassers or ebay and re-sell after. Used good ones hold their value well. At least in the short term. I'd lend you mine but I'm shooting in NY in a couple weeks and then going to the Sierras right after that and am using it both times.
