Just bought one myself so still getting used to it's attributes.
Sure you will get some mixed responses regarding target use (from great to not the best), but I like the Alecto a great deal. The trigger is not as crisp as the HW40 but is very nice.
One notable feature for me is that it is easier to cock (once) than the HW40, which is easy enough anyway. Cocking once more is a bit more difficult than the HW40 but well worth the effort for extra power. I find the third pump is too much effort to be worthwhile.
There is a useful review below, which highlights the need for consistant cocking to achieve consistant velocity/accuracy. Sure enough it takes more effort to fully open the cocking lever than on the HW40.
