I have shipped a vision to canada and would not do that again. There are a number of great cages made here and there is no point to paying the shipping and high brokerage fees unless necessary. Greg West is a great guy (Cornell's world) Sly Plastics is also great (web site sucks however) http://www.slyplastics.com. A friend of mine has a PowerHouse cage and it is also quite good better IMO than AP a really well thought out design. http://powerhousedisplays.weebly.com/products.html
Radiant heat panels are great things, I own two. THEY do NOT heat air however (look up RADIANT...) don't take my word for it read the FAQ from one of the biggest manufacturers of them, reptile basics. RHPs can be used to replace UTHs but like UTH do little for ambient air temps.
"...This Infrared Heat tends to heat objects more than the air, much like the natural sunlight outdoors."

Where the idea of a radiant heat panel heating air comes from I don't know, the only explanation is holding a thermometer under it (heating the thermometer) to check air temps (it must be beside it...) this shows a complete lack of understanding of the nature of the product and of the way things heat.
Fun little web explanations ... http://www.wisc-online.com/Objects/V...aspx?ID=sce304
It does not alter ambient air temps much but instead replaces the need of flexwatt. If the room is cool a convection source is still needed they luckily are cheap and easy. Fluorescent lights act almost the same way as a RHP only it is a convection source I use a deep blue (reptiles 'see' deep into IR and less in UV so blue is better than red as red is in the visual range.) LED lights during the night the led emits little heat but the electronics around them do. I measure my FL lights at around 100ºF (maxed, lower than the 160ºF of a RHP) and the blue led lights at 90ºF this helps act as a heat pump to run a more aggressive ventilation system and increase the ambient air temps. I easily hold 12-17 degrees over background. (65º room and I get air temps in between 77-82º) in the summer I have the lights shut down longer periods of time and often during the hottest (brightest part of the day) I don't think the snakes even notice as it is during the sleep cycle for them.
