Netherworks sells at his shop and at Content Paradise. Any of his clothkit scripts except his v4 one will work with any magnets. He also has a free version of the script on Content Paradise

Some day I'll learn python coding sigh

As for a deletemagnets script theres a free one by Ockham I think still in the freestuff here as well as the ones in Netherworks clothkits
