I am placing an order with SwissTropicals in about a weeks time, so if you'd like to join in, please comment or send me a pm.
Stephan has arguably the best poret foam you can find anywhere and it's very hard to come by here in Canada.
Prices are in USD and shipping is $39.00 total. I will split shipping costs evenly among the orders.
Also note that they have many other products you can buy, including complete HMF kits, and you may also customize the size of your foam as well.
So let me know if you're interested.
