if you are just beginning, i really don't think that trying out a number of rods will be the best thing for you. as a matter of fact, if you are really just starting, trying rods would be the worst thing for you; you will invariably get a rod which you will quickly outgrow as your technique improves. like windsurfing, i think that in spey casting, it is much better to get a good rod recommendation from an experienced instructor who has cast many rods, and know which work best for beginners, etc.
for the money, i don't think anyone can beat the cabela's rods. the next best rod for the money would be the 14' or 15' st. croix rods. either of these rod lines will be serviceable for you well past your development into an intermediate caster, and they won't cost you an arm and a leg starting off. if you do catch the bug and get into higher end rods that fit your style, they will still be very servicable as backups.
if you are poaching e-bay, look for softer action quality rods (but not too noodly like the GL3's); good examples are the sage 9140, 10150s, scott 1409, 1308, non-derek winstons. as a beginner, you want to avoid faster action rods like the T&T's, and i think the scott 1509 would be way too much stick for a beginner to handle.
