Standard Length DC 510 cartos

[fright88]

Well I have been looking around for best prices on DC cartos and I realized for the tank I want to use them in I need the standard length Cartos the XL are too long. And it seems that 90% of the sites I find them on only have the XL version. So I was hoping someone could tell me A) where to buy standard length LR DC cartos Preferably Stainless but I can peal stickers if needed (no clearos) and B) who has them at the best price although I can shop that around.

Thanks for any help.
