Ruger old army blue or stainless

[somtec]

Hi
Iam in the market for getting a couple of these revolvers as i shoot cowboy action with the BWSS, or at least when i get a variation done, and blue ones seem to be the cheaper of the two types compared to stainless.
Do the blue ones need more work in the cleaning department compared to the stainless or are they much the same , basically is the money better spent getting stailess.
As a side issue how much is 1 kilo of lead to buy for casting.
