I am about to order an Opto board for my upper playfiled ramp for my IJ. Marco is out of this and the only company i could find that has this is Great Lakes Modular. Just want to make sure they are a good company. Thanks guys!!!
Buy with caution....
I've purchased a few items from them in the past but support is not that good IMO. I currently have an issue with their Opto-16 board. And the same pattern has occured that I have experienced in the past. He responds once or twice and then stops responding if the problem isn't resolved after one or two exchanges.
If he ever actually resolves my problem or provides a refund I'll update this post.
