WooCommerce Payment Extensions

Hey Guys, wondering if you could provide some advice. Have any of you ever heard of Certoconnect? I was about to buy a few payment extensions for my woocommerce site: Google wallet and Amazon FPS, they are $49 each. However, another extension I found is called CertoConnect and it seems to be one extension that offers a variety of payment methods, among them are google wallet, paypal and Amazon payments. It also cost $49, but I will get a whole mess of payment methods that if I were to purchase them individually would cost an arm and a leg based on Woothemes $49 each pricing.

Am I not getting something? Is there a catch? Is there a reason I shouldn’t buy CertoConnect and call it a day? Here’s the link to CertoConnect info: http://www.woothemes.com/products/certoconnect-payment-gateway/

I hope someone can shed some light. I’m new to woocommerce, and basically new to e-commerce, period. I’ve already wasted a few hundred on a site, and realized it’s limitations. Now I’m building a new site and I don’t want to fall in the same trap again of buying things I don’t need or don’t work. Would greatly appreciate some advice. Thank you!
