Absolutely yes.

And you will discover some pretty good servos that way.

Like the Hitec HS225. They're more powerful than the average standard servos from most mfgs and only 2/3 as heavy as the average standard. And only about $20 each. Great aileron servos. I use them for aileron and throttle and save almost 2 ounces in your average 40-60size model. And Tower gives an extra discount off the price when you buy 3 at a time.

Just about every mfg has a servo or two that stands out. Like JR has an entire line of economy ones. They have a rack in the LHSs with the economy line. Their small 48oz-in servo is great for throttle in the 40-60size models, especially ones that come out tail heavy. I've actually been using them instead of the HS225s for throttle simply because the power of the HS225s is overkill. Doesn't really matter, but it suits the engineer in me better.

Yeah, every brand of servo except futaba will work with any brand receivers and wiring.

BTW, the JR "economy" switch harness is another excellent deal. Bulletproof harness with almost failsafe switch for less money. Suits the cheapskate in me better. And the demanding modeler who wants the best switch possible. (they used to kill more planes than gravity did)
