There are two versions of the 40-150, an older, faster version, and a newer, smaller and slower version. I've heard differing reports regarding which is better, however if in a school hall the older one may be preferable. I have this version, and have been very pleased with it. Having said that, I saw the new version for sale at SRS Microsystems online, at £90, which is the cheapest I've seen it anywhere |
