I've had good luck with the Factory Five Arms. I think they still sell for $199.00 for uppers and lowers. They build them to order so expect some delay.
When I installed mine I didn't have any of the issues you described. They didn't come with the upper axle bushings but I don't think any of them do.
What kind of driving do you do? If you're looking to auto-x or road race, look for an arm with a spherical bearing. Try
