These days, cheap CFLs are getting progressively easier to find, in the common wattages anyway (eg 11W - 20W).  However, it seems that the higher wattages have eluded this market for the most part - not really surprising when you take into account what a small portion of the overall market they make up. 

However, there are some out there if you dig around, this 30W example I discovered totally at random in a discount store when I was looking for, of all things, a box of paperclips!

Technically speaking, there isn't anything particularly special about this lamp, it's a very ordinary compact fluorescent lamp, featuring an instant start electronic ballast, and colour 827 phosphor.

The 8000 hour quoted lifetime sounds somewhat on the long side for a budget lamp, but this lamp does seem to run quite cool - a good thing, as what generally kills CFLs prematurely is overheating of ballast components.  Regular switching of course would not help - but generally the problem with cheaper lamps is that the tube itself will last longer than the ballast.  A far cry from the first magnetically ballasted lamps where the ballast would last effectively indefinitely, hence the evolution of lamps with a separate ballast/tube assembly.
