HT5622 bought from Robert Dyas because it was relatively cheap at under £100 after my Mcallister developed a few faults. A bit nadgery to start and not very well balanced - all the weight is at the motor end which makes it feel heavier than it is and tiring to use for a long time. This might contribute to a rather uneven cut compared to other machines. I have a Mountfield multitool which is well balanced and gives a better finish although not on the original blades (long story). The Mcallister was a real beast and went through everything first time (so you had to be sure you were cutting carefully). In contrast the HT takes a few passes to get things smooth. It has only done a few hours work so reliability is an unknown but I hope it lasts longer than the couple of years the (very cheap) Macallister managed. On the plus side it is quite parsimonious on fuel, does not smoke at all and runs reasonably cool.
