I dont have one, but am tempted as a collector of systems including bootlegs.
I do however had a *real* NES toploader. It works great not having to blow out the games. The picture quality isn't as good as a standard NES with composite outputs though. The real toploaders are RF out only not composite. These bootlegs appear to be composite so it may be a decent buy. If you end up with one, post your opinion.
I normally would take the plunge, but my Ebay dollars were drained into all the parts for my control panel. *Resists using paypal buyer credit*
