Not used one but I read a fair bit about them and decided they weren't that much of a gain for me.
As I understand it, they offer huge performance increases over standard drive if you are only accessing the same files over and over again such as working on office type docs. Once your file size exceeds the cache or you are constantly writing new files (both were true for me) then they are no faster.
So, yes, it is way too good to be true.
I run a 128GB SSD as my main system drive and a second (64GB) for swap/paging files with standard SATA drives for storage.
The lag in picking files up off the SATA drives isn't noticeable enough to bother me once I turned off the power down option of the disks.
My PC starts much faster (power on to Windows desktop ready to use is about 20 seconds) and swap file and Photoshop scratch file activity is lightning quick with full screen filters being applied to 10000 x 8000 pixel images in a couple of seconds
