I groom Flo myself after a few groomer cuts I wasn't happy with (she kept coming home looking over done and like a poodle) and also because of the cost. I spent quite a bit on kit but it will pay for itself within a year then I'll be using it for many years to come. I think there are less expensive options that would also be just fine.
I got everything from
http://www.groomers-online.com, other websites have the same or similar stuff but I've put Groomers links on just so you can the kind of thinds to use.
Andis clippers with a 1.25" comb attachment (which keeps her coat quite long and shaggy. I run this over her back, sides, tummy, chest and tops of her legs

Thinning scissors on top of her head, muzzle and bottom of legs

Ear and Face scissors to tidy around the eyes to keep the hair out and to tidy hair inbetween her pads

Coarse comb to comb her through everyday and before using the clippers

Slicker brush once a week to pull out loose hair. I use a ball pin slicker as it is gentler

Groomers will also trim their nails so you'll need nail scissors. I don't do that as her nails are black and I'm not sure where the quick is so my vet does it for free as part of the health plan she is on.
Groomers also wipe all around the inside of the ears (I use baby wipes) and also sometimes pluck the hairs out of their ears to keep them tidy and less prone to mess and so ear circulates. Although I don't need to do this as Flo doesn't have any hair in her ears.
Mikki is a lower priced brand which is OK but if you have the budget go for the professional equipemnt as it lasts much longer and is much better quality. I have used Mikki and Roseline thinning scissors and Roseline are far superior.
Because I'm not that experienced I tend not to go for a great long session where I do everything but just do bits as I go along. Last week I tidied her face, this week I'll run the clippers over her back and sides then next week I may scissors the lower half of her legs etc..
This is how Flo looked after the groomers cut - arghhhh (nothing against poodles and no offence intended to those who prefer a tidy/poodle cut but I prefer the scruffy look on Flo)
And this is Flo after my 'tidy up'. A bit more relaxed and scruffy...
