What upgrade will give me the best "bang for the buck"

[awesome_welles]

At the moment I have a Technics SL-BD22, Arcam Aplha 3 amplifier, Wharfedale Denton 2XP speakers which I bought second hand and cost me about £35 each. My stylus is an Audio Technica AT-92E (with an elliptical stylus). I have a bottle of record cleaning fluid and a cloth but I mostly use my microfibre brush. And I have a little stylus brush and liquid similar to this:

Would either of these be a useful investment?

• Knosti Disco Antistat Record Cleaning Kit (£39.95 with free delivery on eBay UK)
• A tracking force guage (the SL-BD22 is factory preset, does that mean that it'll always be correct or shuld I check it?)

And are there any better cartridges out there for a similar price (£20-30)? From a bit of forum browsing, the Shure M92E doesn't seem to be considered better than the AT-92E.

A Shure M97xE cartridge will track better than the Audio Technica, which will give your LPs more protection from being chewed up. However, it costs $89 (£50 ?). Might be worth considering.

The Disco Antistat (German piece of kit) is quite effective but is a bit of a pig to use and can end up messing the labels of your LPs if the liquid leeches through the clamp. Mine has been gathering dust for years !

I forgot to mention that it's a P-mount turntable!
