Which combi boiler?

I have a Puma 80 combination boiler that is about 7 years old and has been going wrong 3-4 times a year since I've had it. It has just gone wrong yet again and I've finally had enough. Can anyone give me any advice about a good, reliable replacement - which makes are best and what should I be looking for?
Thanks,

If you look on this forum 90% boiler problems are combi.They were ordinary design for tower block flats with no loft space for water tank & space saving for cylinder,then started to installed them in bungalow and then onto family 3-4 bedroom property.My potterson floorstanding boiler is still going strong after 23 years compare with combi lasting according to this forum 7-8 years.My parent have a valliant boiler which take 15 minutes to fill up the bath because of low water pressure and has broken down 4 times in 3 years.If you listen to everybody opinions you wouldn't buy nothing ! Don't let me put you off buying a combi as they are getting better all the time,I probably will buy a combi next time but personally I don't think the combi manufacter have got it quite right yet but they are economical and some happy combi owners out there.This is personally my own opinion.
