Stainless steel equipment
I hope you'll forgive my little advertisement here and that it could be of use to you.
I'm located in Vietnam and have a welding workshop, we build various kinds of devices and basically you can just send me your drawing and have it custom made and shipped worldwide. The thing is stainless steel and labor are very cheap here and that may help you build your dream lab (bioreactor, heat exchangers...). So, when you have time, have a look at :http://www.stainlessstuff.net
PS: I studied 3 years of biology, and when the time comes will have my garage lab too
