I bought an on-one tensioner that looked solid and has a nice bearing roller. Bloody thing wouldn't fit my dropouts! They were designed for flat / stamped dropouts, not cast alloy ones.. AND they are designed for quick release wheels. I got it to work after extensive filing.
But it is a solid piece of kit, and I reckon the 'push-up' type (that tension a chain upwards) are nicer than the ones that give you less chain wraparound. BTW I used a hacked up derallieur for ages - if you are not worried about looks then it works - endof.
