Velleman vs Weeder vs Addicon


Senior Member
Anybody have pros and cons on Velleman vs Weeder vs Addicon for cheap inputs and relays? Assuming this would be used with a PC based system and would need to scale to around 100 inputs and 30 outputs, which is the cheapest, most reliable option?
I'm only familiar with Adicon - you're looking at around $800 for that number of i/o with the controller. Don't expect snappy response from the i/o
I was kind of leaning towards Weeder both in terms of cost and response time. I'm hoping somebody has some first hand experience with these boards.
