Question for sewing-savy friends

Lisa and I have decided that we've hit the point where it's going to be worth our while shelling out the money for an overlocker (read: Lisa is currently mid way through making this dress, and anything that makes the rest of the job easier has got to be worth a little money). Trouble is, we're not really sure what to look for in a good one without spending exorbitant amounts - so up goes this post to check whether any of our many wonderful cosplayer friends might know more than us about the subject and have some advice to share.

The overlocker we're looking at is going for about $500 at Spotlight. Finding any info on whether it'll be a decent machine is proving trickier than it should be, however, since just about all the pages we've yet found which review overlockers are American, whereas one of the few things we've managed to find out about this brand (Toyota) is that it's sold mostly in Europe. So, does anyone know anything whether this is likely to be a good brand to go for? Or does anyone have any other suggestions about machines we should look for which won't be too far outside a reasonable budget?
