Powerful, effective, and good value for money.
I bought this machine because the angle-head gears in my Efco 8250 Ergo had stripped. Tried to get the parts, but Efco don't support machines older than 5 years, so beware. The rest of the machine's fine, so where's Efco's claimed environmental responsibility there, eh?
OK, sermon over, and as the above machine was probably a bit light for my place, I decided to go for the Stark 44. What a difference. (The machine delivered is actually the Stark 4400, probably the later model, so bear in mind when comparing with other sellers) The extra power keeps the speed up, and so far it seems to get far less material wound around the head, which was the biggest headache with the previous machine when doing heavily overgrown areas. I assume this is because of the continuous high head speed.
It's much more sturdily built than my last model, and consequently is somewhat heavier, but if you spend some time getting the adjustment of the handle positions to suit you, it's comfortable and well balanced, and I hardly notice the extra weight after a while. And, it's an excuse for an extra pint after a hard day's strimming.
All in all, so far I'm very pleased with it, and the MowDirect price and service must be about the best you can get.
