I figure it's time to buy a dedicated programmer and looking at the Arduino IDE is seems to natively support AVRISP, USBTinyISP & USBasp. Could people please suggest the most suitable/versatile of these to buy. It will probably be a cheap eBay device unless the cheap devices are unreliable.

Recommend a USB programmer

Bought one of these a couple of years ago and it has served me well:
