I've also not bothered with UV filters for ages. But polarising filters are useful.
I did once while on holiday in the USA buy a similar twin pack of UV and polariser made by SunPak. The polariser did the job but I've not used them in years.
Hoya seem to be the average standard for consumer filters. Decent enough quality and not too expensive.
I'd say, use the cheap one, if it's ok then fine. Chances are if you get seriously into photography, you'll want to upgrade your lenses, so you'll need to get bigger filters at that stage anyway.
For example a lot of beginner kit lenses take 52mm or 55mm filters, but if you upgrade your main lens, you may find you need a 67mm filter.
