They are still available, but not stocked in NZ now because of the noise issues (R304's are 102db). You can still get one if you order it in specially, so not much chance of a cheapy unless you can find a used one or a dealer who wants out of one they have in stock.

Price is the same ($299 most places) and there is a slight difference in power in that shorty silencers make better low to mid power and the longer ones are better mid to upper as a rule. Apart from the noise most people probably wouldn't notice the difference.
