In my area we don't have a lot of overlap between the league players and the regular pool hall players.
The league players run the whole gamut: very few have jump cues, and most of those are jump/break, not dedicated jump cues. Honestly, I've never seen anyone but me jump a ball in a league game. About half the players have separate cues they use for breaking, but very few of those are "real" break cues (meaning they are designed for the break or have special tips). The other half just have a playing cue, some of which are used for breaking and some use just house cues. We even have a handful of players who just use house cues all the time.
Almost all the regular players at least have dedicated break cues. More than half of those are jump/break. Maybe 10% have dedicated jump cues. The guys with jump/break and jump cues definitely have an advantage when the need arises. I've gotten out of plenty trouble and even won some games/matches because I can jump, both close and far. Very few of our regular players have just a playing cue, although there are a couple that come to mind. For them, breaking is not a particularly strong part of their game, and jumping is essentially out of the question, but they still manage to play well and compete.
Having a break cue that is designed for that purpose, even a cheap one, seems like a worthwhile investment to me. A jump/break is probably the best bet for a recreational player, both value and flexibility wise. A dedicated jump cue is a highly specialized item, so I would do without that until it gets to the point where you honestly think it can help your game.
As for me personally, you can see in my signature that I have both a jump/break and a dedicated jump cue. For most jumps I use the dedicated cue. My j/b has a jump extension on it, so for full table jumps I use that. I also have a Jump Caddy bridge head (and my own bridge stick), which helps tremendously with bridge jumps in the middle of the table. So I definitely use technology to my advantage when I can.
