Any Brush Plating Kit Recommendations?

Hi Everyone

I've been doing some electroforming of objects to turn them into jewellery. They're ok but I'd like to try some plated in silver over the top too. I've been looking at brush plating kits - seems the easiest & most economical way to do it but wondered if anyone had any recommendations with which manufacturer to use? There is the SPA one which is £200+, Gateros do a basic one for £50 and Classic plating do one for £45, all seem to be very similar but the Gateros one is definitely cyanide free (the others don't specify). The SPA one, is just too pricey for me. Does anyone have any experience with them?

Thanks! Jen
