It really depends on your definition of cheap and what materials and equipment you already have. The following sites and their links should be of some help as to what is involved.

If you're only propagating a small number of plants the premade media are probably your best bet. I've tried the home made, fertiliser based TC media. They work OK for seed but you really need hormone supplemented media to do mericlone work well. The first webpage recommends Sigma and GIBCO media. Forget sourcing from these guys. Most of the big laboratory suppliers will not supply home users. I'm sure there are others who can supply media but as far as I'm aware you shouldn't have a problem sourcing supplies from Kitchen Culture Kits and or Carolina Biological Supplies. FWIW most cp's do well in 1/2X MS media + whatever hormones and biocides you want to put in(charcoal is generally not needed).

Realistically you may be looking at spending a couple of hundred dollars at least in set up and media, especially when you consider the finetuning of your sterile technique. Ongoing costs are of course cheaper. It may end up cheaper to send the plants to a commercial flasking laboratory for propagation (eg an orchid flasking lab). Head over to the GW Orchid Forum and ask if there are any labs they'd recommend. They may seem expensive but they generally work out cheaper than a once off DIY venture.

Now all we need is Sheldon and we'll have a full house. :)
