4yanx experience mirrors my own.
I used to use LAST record cleaner and preservative back in the '80s for most of my records. (I probably used it for 5 or 6 years, and put it on at least a hundred records or so.) In the '90s I switched over to CDs (like most of us I imagine), and did not get back to my vinyl collection until 3 or 4 years ago when I bought a new TT and phono preamp. When I have played those records with the LAST preservative, I have found that they still sound great.
I now use a RCM, (Nitty Gritty 1.0) so I have not found the need to utilize the LAST products. However, based upon my past experience with them, I can recommend them if you don't have a RCM. (Personally, I think a RCM (even a cheap one) is the best alternative to cleaning your records. But if money is a concern, the LAST products are pretty good. If you do get a RCM, the RRL Super Vinyl Wash is very good, and I highly recommend it.)
As far as Stylast, I tried it, but did not really feel it did much. So I too now use RRL #9 as a stylus cleaner, and feel it does a good job. (I actually put the liquid on the brush, rather than on the stylus, in order to minimize the amount of liquid that goes onto the cantilever.)
My two cents worth.
