At minimum, make sure they let you test cast it.
Better yet, let you test cast it on water.
I'd check out any fly shops in your area, and then head to Cabela's.
Try everything that fits your budget, and a little bit higher, to see if one of them meets your requirements.
I did this myself, testing every rod I wanted to at Cabela's on the grass. I eventually left with something, but when I finally tried it on the water it just didn't seem to meet my needs.
So, I went to a local fly shop, and I tried a rod on the lawn. It didn't quite seem to be what I wanted, and it was way over my price limit, but I decided to try it on the water.
...Worth every penny, to me. It was that final step, of actually puttig it to water and giving it a workout where it mattered that made it come alive. Sure, I spent over 2x what that Cabela's rod cost, and I spent 50% more than I _ever_ intended to spend, but it was worth it. I took the Cabela's rod back that weekend, and used their iron clad garuntee to get full value in return (I made sure to keep the plastic on the cork and try to not get the rod dirty because I expected it might go back).
So, I suggest you find some local shops, whether they're independents, Orvis stores, LL Beans, or the big box shops. Ask to try, and ask what the return garuntee is, and buy what feels good to you.
The right rod makes all the difference. The reel? It holds line. I've got an expensive one that mimics a cheap one because the price was too good to pass up. I've been usnig it all this season, and I haven't put a fish to the reel yet, my fingers do all the work.
But hey, if your SA reel is a click-pawl and you don't want it, send it to me when you're done. I had to spend alot to get an old clicker.
