we usually stay at the Park Inn, usually for about £60. Probably just because we always have - although it is a decent enough hotel. Rooms are always really nice and it's the first stop on the Hoppa! (Very useful when returning back to LHR on a busy morning)

There's a pub over the road where you can get a cheap pint and reasonable pub fayre (with a 'y') for buttons compared to the hotel prices.

I also really like the Radisson Edwardian mainly for it's bizarre seats in the bar. Haven't returned since using it prior to a skiing holiday when I injured myself - am quite superstitous when it comes to this sort of thing.

Flying ex-T4 I think the Hilton is a no brainer simply because to get from Bath Road it is Hoppa + HEX as far as I recall.....
