Andrew,
You can find your chemicals on eBay from quartzpegmatite at very reasonable prices and shipping costs,
http://shop.ebay.com/quartzpegmatite/m.html?_nkw=&_armrs=1&_from=&_ipg=&_trksid=p4340e.g.,
Thiourea 98% Lab Chemical One Pound --> $11.99
Stannous Chloride Anhydrous 98% 1/4 lb --> $8.99
Sulfamic Acid 99.8% Lab Chemical One Pound. --> $5.99
I have ordered ammonium dichromate from him. In my order, he enclosed a rather extensive list of chemicals that he sells direct and not through his eBay store. I haven't found better prices on chemicals. For example (from his list), mercury metal, 99%, 2 lbs --> $25.00; The science Company sells 250 gm for $52.95.
