I know this is beyond the stated budget, but I have been using an Audio Technica AT150MLX for 2-1/2 years on my SL1210 M5G and it's a *great* match. I mounted it on an LPGear ZuPreme headshell, which is more rigid and non-resonant than the stock headshell, and its extra weight helps match the AT150MLX's compliance with the Technics arm's effective mass.
The tonal balance is very similar to the Denon DL-110 (I used a Denon DL-160 for a year before switching to the AT150MLX), but the AT150MLX pulls way more music out of the groove.
Another possibility is to get a Shure M97xE for around $59.95 and replace the stylus with an aftermarket Jico stylus from LPGear. A couple of A-goners have gone that direction and are ecstatic about the results.
Another thought: KABUSA.com has the Ortofon Concorde cartridge/headshell units upgraded with Ortofon audiophile (i.e., not DJ) stylii
here. Getting one this way removes one of the physical connections and ensures that your overhang is as aligned as it's going to be.
