Mr. Conga,
For local gigs or band practices and for my cheaper congas, I use Gator softcases. Yes, I got them when they were on sale at Musician's Friend at 2 for the price of one (around $60 then). I love the wheels which make transporting much easier, but I wish that they have thicker padding for greater protection.
For my top-of-the-line congas and gigs where I anticipate that someone else might be handling my congas, I use hardcases--Humes & Berg Stealth, also with wheels, which I got for a very good price (close to the best softcases).
There are many other good ones. Humes & Berg softcases (the over-$100 Tuxedo model or the under-$100 Galaxy model) and Beato come to mind. And they're both made in the U.S.
Protection Racket conga bags (made in the U.K.) are good, too. I like their sheepskin-like interior lining and cushioning, but they're priced above $100 each.
I once ordered Meinl conga bags (made in China), but I returned them not too long after. I liked the thickness of the material and the padding and are reasonably-priced (less than $100). However, the quality of the stitching wasn't good. Same with Gon Bops (although 4 of my congas are Gon Bops CAs) and Pearl bags, which are also Chinese-made.
Resolution's bags, are made by JP Cases in Southern California. Unfortunately, I believe that they seem to have closed shop or, at least, you can't order from them directly anymore. They no longer have their old website. I was interested in them once. They're very well-made and the materials are excellent (I know 'cause they made the softcase for my Fat Congas Cajon), but they were rather expensive--over $100--for softcases.
Given your situation, I'd recommend looking into Kaces softcases. Musician's Friend, Music 123 and Interstate Music, to name a few, carry them. Musician's Friend and its sister company, Music123, both sell them for "only" $64.99. Check them out at:

Hope these help and good luck,
