I think the scorpian set will be fine for you what need. It will be a nice starter set. I love their shears. But then again, shears are very personal to the groomer, so one groomer may love a shear another dislikes. I've picked up Chris Christensen shears and they seem heavy to me. Kenchii is very lightweight. The only difference between the scorpian and spider is the material of the shear. You can upgrade later on.
I own a very nice convex edge shear but only used that during competition. I have never really needed a convex edge shear for pet clients because 1) takes more time to scissor, and 2) most pet dogs do not have the hair to get a nice finish (many pet poodles have wispy, floppy hair). So my beveled edge shears does just fine, and it actually "lifts" the hair as you cut, so it is good for drop coats.
For a stand dryer, I like the Edemco brand but they can be pricey. Whatever you do, don't get the Master Equipment PowerDry. I have that and although I like the actual dryer - it can double as a stand dryer or a force dryer because it is variable speed and comes with a stand you can mount or dismount the dryer on - the little plastic insert that goes into the base is a poor design and has broken on me twice! Now I have to get things from the hardware store to add onto the base to make it stand again. To save money, maybe you should invest in a CC variable speed force dryer. I have used the Kool Pup (I think) and it was nice because you can turn it down low and use it almost like a stand dryer (you'll have to get a clamp to hold the nozzle if you plan to brush at the same time) or you can use it as a force dryer.
When I learned grooming, I was never taught how to use a thinning shear! I was also taught just one way of doing a teddy bear head - short and ugly. For ALL breeds! And one style of poodle topknot - short. I developed the style I liked by looking at videos and pictures. The thinning shears does add on extra time to your groom so just be aware of that. I usually use snap on combs to block in the face, scissor sticky outies, then finish up with my thinning shears to blend everything (this is on drop coats). You can also use snap on combs for curly coats, but you always want to use scissors to finish the head.
You can purcahse Jodi Murphy DVDs on shears, snap-on-combs and thinning shears (3 separate DVDs) if you want to watch some videos. Or learn2groomdogs.com has many videos you can watch over and over again for a monthly fee of $42/month.
Some grooming items I can't live without (besides your typical clipper and blades):
- kenchii spider set (8" straights, 8" curved, 44-tooth thinners) (beveled edge)
- Bravura mini (non-adjustable #30 blade)
- Les Poochs matzapper (I use this A LOT - I want to be buried or cremated with this brush when I die)
- CC poodle buttercomb
- 3-4" blunt tip scissors (great for cutting out mats or trimming ear the eyes)
I've tried a Chris Christesen slicker brush and it was really nice! My future purchases will be the CC slicker brush and a CC comb that is fine tooth. I also want to get another LP matzapper, and I am looking at their greyhound comb. I also want the Wahl Arco.
For shampoo, I love Chris Christesen products for drop coats and curly coats. For bath dogs, I use Show Seasons products.
