It'll be half baked Chinese shite that doesn't work properly, that they normally sell on ebay.
There's generally no need to have an SSD external drive because you don't tend to use it enough to benefit, and you usually connect it by USB anyway (which is too slow not to be a bottleneck for a normal hard drive, never mind an SSD).
But as an internal drive they can't be beat, as long as you get a decent brand with one of the modern controllers (Marvell, Sandforce or the latest - not earlier - Samsung). Worth every penny. Putting one in my notebook was the best thing I ever did, it was like I'd upgraded the whole thing with a turbo model. Everything's instant.
As well as the raw speed increase, you also benefit from the lack of a physical hard drive head that has to be moved around, which massively improves multitasking. That doesn't get mentioned much in reviews, but it's beautiful - I can run a sector by sector backup of my SSD in the background, while working on fairly disk intensive things in the foreground, and you can't even tell the backup is happening. On an HDD it would slow things to a crawl, as both workloads keep pinging the HDD read/write heads all over the place.

USB flash drives don't have sophisticated flash controllers inside them. If you repeatedly write over the same area of the flash (eg. keep rewriting the same files), you may wear it out.
SSD's have very clever controllers though - they have sophisticated methods of rotating writes all over the flash memory (amongst other things), to spread the wearing effect out, making them last much longer - many years in normal use.
It's very unlikely you'll have a write fail of that type in the lifetime of an SSD. And even if it happens, you don't lose access to your data - read still works (unlike HDDs when they break).
