Shimano RSX Shifter replacement

I just purchased a Diamondback steel road bike. Seems to be in good shape, except the shimano rsx shifters need to be replaced. Derailleurs seem to be fine. What is a decent quality replacement for these (3 x 7) shifters? Keep in mind that this is a 20 year old bike. I want to ride it, but I don't want to spend a boatload of cash fixing it.

Might just need some clean/lube on the RSX

Besides Tourney, there's also the Microshift R7. Brand new, they'll set you back about $80 for the set.
Really, any -7 or -8 speed shifter will work; with an -8, you'll just have an extra 'click' that you won't use.

Ditto, the MicroShift. I just put a set of MicroShift 2x7 on my older Trek 5900 to replace the Dura Ace downtube shifters. The new shifters work great. Better ergonomics than the hooked aero hoods on the old brakes.

Installation and setup were pretty easy, not really any more complicated than installing downtube shifters and separate brakes. The precut shifter cable housings are nothing fancy but work. Eventually I'll replace them to match my custom cut brake cable housings.

No problems indexing on my 7-speed 14-28 Shimano freewheel. I may have done a minor tweak to the barrel adjuster but the basic setup from the Dura Ace indexed downtube shifters was fine.

The left side/front derailleur indexed shifting was surprisingly good. I'm accustomed to friction shifting on the left. The MicroShift has a trimmer detent to nudge the front derailleur slightly to reduce chain rub as we run up and down the rear cogs. Once I got it dialed in it's quicker and easier than manually trimming friction shifters to reduce chain rub.
