Good value lipo charger for tx batteries

[RobW]

I need to buy a lipo charger just to charge my tx lipo battery - I've got 2 decent chargers (pro-trak) to charge my race packs but they only seem to charge 2 cells.

Don't want to spend a fortune as it will only be used every 2-3 weeks to charge my tx but equally don't want to buy rubbish. Needs to be able to charge 3 cell lipos and ideally have some sort of display as I want to know what it is doing and how much capacity I am putting into my cells.

So far for around £20 to £25 (in UK) I've seen:

Imax B6
Turnigy Accucel
HK Variable

Anyone used one of these and got a view?

Cheers

Rob
