I'd suggest a three headed Philishave rechargeable model. Theres an entry level one about 70/80 euro in ireland. I got mine in Germany for about 10 euro cheaper than I've seen it here.
The basic requirement for me is three heads, a trimmer on the side and rechargeability
More expensive ones have built in moisturisers and are waterproof but I dont think its good value as the price leaps up if you go beyond the basic requirements.
I've noticed with Philishave the first thing to go is the plastic connectors around the cutting blade or some weak part of the head itself. The circular blades can be replaced (new ones were about 10 euro in Germany, I dont know what they are here) and the motor will work indefinitely so when cleaning them its important to be gentle if tapping the waste out otherwise the plastic connector can crack due to fatigue and you will pay over the odds to have it replaced because it can mean replacing the whole head. If you protect the plastic connector parts which hold the blades in then Philishave should last for years and years.
