I've had LASIK (
link) in March 2017. As for your questions:
1. Very positive experience. The aftercare is fairly long and involved but you get used to it. 8 months later my vision is actually still 2 steps than 20/20 vision in the eye tests. If there's any downside, it's one for other people because, if you're like me and you've been wearing glasses all your life, you have no frame of reference for what you should be able to read or not, so you'll be asking that a lot :P
2. I paid about €3300 for the procedure. This includes the surgery, aftercare and lifetime warranty (meaning they'll touch it up for free as many time as necesessary).
3. Ive had the LASIK with iDesign + IntraLase + Advanced CustomVue Wavefront from OptiLase. Essentially that means it's bladeless and your eyes will be fully scanned and mapped beforehand to correct any individual imperfections specific to your eyes.
I would echo that you should consult a professional about possible side effects, such as possibly still needing reading glasses. Your surgeon should (and mine did) point out to you beforehand that many people will need reading glasses even after they had the surgery. However, most people don't need these immediately but only much later with advanced age. If you're an older man/woman/whatever already, it is quite possible you'll need them immediately.
