Hi Wizzel,
You can also try the Trumpeter Riveter. It has three/four different wheels that fit in the handle for different spacing and scale.
You use it by drawing the 'wheel' along the line where the rivets are to go, and it leaves small impressions in the plastic representing rivets.
I tried it on a 1/48 Sea Fury and got some good results. It is a cheaper option to that you have mentioned I believe and probably on the basis of 'you get what you pay for' then not as good. But it all depends on your skill (or in my case lack of it) level and perseverance.
Cheers,
