I can't decide between the Happ Competition and the Sanwa JLW-TM-8. Most of the games I will be playing will be 4-way, but I would like 8-way available if need be. I prefer ball-tops, so I know the Happ Comp won't be to my liking as much as the JLW, but I can always modify it to have a ball-top for about USD $3.00. So, which should I buy?
