Maruis are the best built and most reliable. I also love the built in red dot scope. The e90 by Echo just looks like a cheap piece of crap. Usually echo is halfway decent for the money but for this series I wasn't impressed. I guess I have bias because I have had my marui p90 since March 07 and it's still running smooth.
The E90 is fabulous, it has a nice finish, and a full metal reciever, the gearbox is nicely tuned out of the box, the wiring is on par with the rest of the echo series, and it is shooting nerely 400 out of the box, repeated results of 370-380. Though fps is't anything. You may love your reddot, but from what I have heard, no offense, the Marui reddot sight is a piece of crap, there are also no replacement lenses for it if one breaks. ( If a company is making them, i haven't heard, so let me know) The marui is a marui, and therefore you are getting a low fps, though highly tuned piece of equipment, for a large price. If you have the money, and have a hard-on for a marui, go for it. But I will always recomend the E90 above the Marui P90, and both over the CA sportline. The CA pro may be good, but im not holding my breath. I would highly recomend that you go try out an Echo 1 E90 today. And, while i can't vouch for the length of time yet, it has been going strong since I bought it, a few days after its release, which, If i recall correctly, is almost 4-6 months ago. However, if it lasts like my other Echos, I will be happily using it for years to come. I have used both for a decent amount of time, and this is my opinion. However, whatever you use, i'm glad to know there are more and more p90 useres out there, keep on rocking!
