I don't know anything about the Megan Racing stuff in particular, but here's what I've learned about coilovers over the years:

You tend to get what you pay for. Cheap coilovers ride like cheap coilovers and break/wear out quickly. IMO, the cheapest I'd go for coilovers is $1500, and the Tein Flex's are *awesome* units at about that price. If you need to go cheaper than $1500, get some good lowering springs and some matching struts. (Edit: Cody's spot on w/ the AGX + Eibach springs... you won't have the ride-height adjustment, but the car will be lower, stiffer, *very* streetable, and have 4-position rebound adjustment... a great setup.)

Coilovers are always harsh. If you want a car that's lower and handle's better, it has to be stiffer. There's no such thing as a coilover that is adjustable enough to give stock like ride on the street and kart like ride on the track. Unless you're willing to drop big bucks on some dampers that have a huge range, and are willing to swap springs, it can't be done.

In addition to the installation issue you mentioned (installation really isn't that hard... installing springs is more work), you should also realize that you'll probably need camber bolts to keep the rear tires aligned properly, and you may need top mounts specific to the coilovers.
