I've owned a bunch of Rega turntables over the years and currently have a P8 as a second turntable.
If you're not concerned about sound quality, there are plenty of options. But if you want to preserve the sound of the stock P8 - which is understandable because it sounds best that way - there are not really any viable options.
A solid mat like the Funk Achromat will solve your static issue completely, is within your price range, and some people even think they sound good. (I don't, I think they sound awful). A cork/rubber mat from ebay is cheap and will sound adequate (if different) and solve the static issue. You could also try the original mat for Nottingham Analogue turntables, which is quite good and a bit closer to the sound of the stock Rega mat: https://www.ebay.com.au/itm/202958473635?hash=item2f414489a3:g:ljUAAMXQkl9RbWsp&frcectupt=true
Alternatively you could try some thin double sided tape on your platter to hold down the stock mat. Also, vacuum clean your records frequently, which does tend to reduce (but not eliminate) the static issue.
