Lots of great pins for 4000 or less. It helps to get out and play pins. The more the better. Some of my fav pins are ones I had little interest in until playing. Sometimes it is the opposite. Think I am really going to like a pin but not so much after playing a bunch of games. GB is an example of that. Looks awesome and packed with features but gameplay soured over time. It also helps to learn pricing so you don't get ripped off. Condition is very important and some problems that seem huge are easy to fix.
