No, I don't. Not that I have anything against lovebirds, my all time favorite bird was a lovebird, it's because you've mentioned that you have a budgie and that you want a buddy for him. A lovebird is more likely to attack a budgie than buddy-up to one.
Of course, if you want a lovebird and have no expectation of it getting along with your budgie, then get one, provided your life circumstances allow for it.
