ZAC-19 sounds like A Weinmann Rim... They're OK For the money but the ones I have here in my shop don't have any Eyelets... plus I'm still waiting to see how they hold up longer term with the MTB folks buying them...

I'd almost say to see if you can hunt down some SUN CR-18s. They've got eyelets, and I really like sun stuff for the factor of being able to beat the living tar out of them. If you're looking for thinner rims than the M-13II would be a good option.... in either case I'm betting the price will be somewhere around the rims you mentioned.
