I have seen that a lot of projects uses scn5 linear actuators, they are kind of expensive compared to wiper motors, at first look, they seams to have better performance and weight moving capacity, but... i just saw in ebay a big range of linear actuators... from other brands or kinds, that were cheaper... this kind of actuators can replays the scn5? for example: http://www.firgelliauto.com/default.php?cPath=69
obviusly there has to be a reason for the price, but what is the reason??? does anybody knows why scn5 are that popular in this comunity (and why are expensive)?
