I have a flash dryer like that one, with the stove heating element that I started out with with plastisol inks. It worked great for flash cure between colors, but for curing the inks it didn't work as well because the heat from the element was not even. I had problems on larger prints fading, just on the left side after a few washings. Turns out that area of the shirt was getting less heat on on that side of the dryer. Then I came across a good deal on used Ryonet infrared Flash Dryer, it heats faster and temperature is even across the entire surface. I still use the oven element for flash drying on the platten, and use the infrared dryer set on a seperate work table for final cure of the shirts. Hopefully soon I'll finally be able to upgrade to a conveyor dryer.
So yes it should be a decent dryer for the price to start with just make sure the entire print area gets up the the proper temp.
But an infrared element flasher dryer would much better if you can afford it.
