I've been reading the older threads, and since the last one i found was 6 years ago, I'm looking for suggestions.
To be clear, no EMs. Nothing that's in the top 100. Only machines that can be found cheaply - meaning you get far MORE value for your dollar, not that it's just cheap. Finally, undervalued is different than underrated. Value. An expensive pin like Avatar that gets no love is not undervalued for this discussion.
In the past, machines like Congo, LAH, etc., would be considered undervalued. Many on the older lists are no longer "undiscovered". So your thoughts? I'll suggest Baywatch, Frontier, and the butt-ugliest pin on the planet, Genesis.
