I did two BSDs with Radcals; I bought a set of decals but they were crap.
The Radcals colours looked great to me. I did a full cabinet restore first and carefully cut all holes with Forstner bits. I think they look very good.
However, there are definitely caveats to them and if I had confidence that I could get a quality set of decals I'd probably use those.
The main caveat is that the Radcals go right to the edge of the cabinet, so there can be overhang if you have any rounded corners. I didn't have the nerve to try to trim them but would like to hear good techniques to do so. You also have to be careful to not overtighten the cabinet bolts or they will warp the Radcals.
Also the original decals for BSD were not aligned properly between the sides and the front. The Radcals "correct" this by zooming the front a bit so they line up -- but then the bat icon doesn't sit centered over the start button any more. You win some, you lose some.
Personally, I think they look stunning on BSD.
