I have more than one Floyd original in more than on guitar along with more than one Ibanez with stock trem (Edge, lopro, edge zero). I have found none of them to be inferior to a Floyd Rose. In fact, I think the Edge series of trems is actually very comfortable, along with being a ERY stable double locking platform. I have an RG450 that has one of the non edge Floyd licensed Ibanez trems. It works as well as any Floyd I have, contrary to what you see others post in various forums and reviews. One thing to keep in mind is that not all reviews are posted by people who actually have an instrument, etc. Sometime they are brand loyal people with nothing better to do than to slag anything that isn't their brand. I know that I am posting this on the internet, but I am going to tell you to not believe everything that people post on forums. There is a lot of bad info.
I would check out the ESP offerings, as well as the Ibanez, or Shecter stuff. I can't really fault any of them as far as their mid line to higher line stuff. i have a couple of LTD offerings (GL200-k because I can't afford the ESP Kamikaze, and an MH1000) as well as Ibanez (RG 550, 450, and 220), and can testify that both are pretty good (except for the pickups in the 220) guitars for the money, and are light years over what you could get in a mid line back in the day. Alot of the metal instrumentals I record are on a Big Apple Strat. But..... I had to spend some extra time, and coin installing an LSR roller nut and locking tuners to keep it from falling out of tune from just hand bends and vibrato, much less using the trem. That being said, with the Beck treatment, it is as stabile as a double locking guitar. But with that guitar, you would be back in the same universe as the Charvel with the big chunky neck heel. Even still, once you are used to it, you adapt. It took me time to get used to the smaller heel after growing up with guitars that had the big chunky neck heel.
If you like the Shava Ibby, then go for it. You won't be disappointed.
