Charger/ cell Ideas?

[ralphee]

Hey guys

OK ive been out for a long time and so much has moved on.
I need a good charger, but dont want to break the bank too much!
Looking at spending around the £70 mark on something that may charge, discharge and maybe balance?
Id seen a 601BC unit on ebay and wondered if this would be any good?
Its a lot different to the Millenium i used to have though.
If not, can anyone point me in the right direction, id like something AC/DC if poss.
Also, cells, what a safe bet to buy for racing nowadays, ive read the poss rule changes but i could do with a few packs to get me rolling, so 3700's maybe?
