I've owned 2 different RCs. The first I had was a 1983 kit and it sounded awesome. Then it all got stolen except for a 12" tom and a 16" floor tom. I ended up buying 3 more matching toms for it and a gretsch bass drum to go with it. Probably the best sounding toms ever made imo
You should consider a few things when you buy these drums though. I've found that if you buy each drum individually, you can find really good prices for them. And the finishes Yamaha uses will usually always match pretty well between individual drums, especially if you go with black which is really easy to find used. Plus if you went this route you'd be able to pick the exact sizes and depths of each drum. Maybe you should look into how much it would cost piece together a used kit.
Another thing is that you might want to compare the bass drum to other bass drums. It sounds weird, but a lot of professionals will use RC toms with a different bass drum. I've heard of pros using a maple custom bass, or I've heard of one using a PHX bass. They've said that the don't like the sound of birch that much in the bass drum and like the sound of other woods better. I have an old gretsch bass drum that I put recording custom lugs on. Unless you see the gretsch badge on it you wouldn't be able to tell it wasn't a Yamaha RC bass, so it matches my kit perfectly, but it sounds better imo. Nothing is wrong with the RC bass, just I think other bass drums sound better to me.
Another thing that you might need to know if you're looking into RCs are that the newer Chinese kits and the older Japanese kits are not the same. Different wood is used and it is made in a different factory, so they sound different. Whether one is better, worse, or very similar to each other I'm not sure because I haven't played a new one yet. Just keep that in mind when you are looking into it.
The last thing I want to say is, I think the price is a little high. I've seen RC kits owned by professionals that were only about 30% more. I saw a Steve Jordan RC kit from the 70s with a beautiful sunburst finish that was pretty close to that price, and I saw two kits go for sale on reverb.com by a drummer who's name I can remember. I think it was Russ something? Both had custom finishes and sizes and they were way bigger kits but not too much more than what this guy is asking. I think a sunburst kit is for sale in the classifieds on the site for less than the kit your talking about.
Sorry for the long post, I just really like these drums and I want you to get the exact kit you want. Compare sound and price and find the kit that works the best to you
