I love Kajabi because of the almost all-in-one features for your online business and the continuous improvement they are doing. But if you're just starting your business, the price could be a bit of a setback.
That's why, to help a potential client to get started, I told her to take a look at Mastera and get at least Tier 2. It has all she needs for the LTD price of 1 month that of Kajabi. I also bought 3 codes for myself so I can have a look first hand. I've yet to explore all features but Mastera really looks promising (waiting for the PayPal integration). I would be recommending it to others as alternative hosting for their digital products.
