Default Blade 4503D Stock ESC/Servo Replacement, Whats the best bang for the buck?

Today my ESC stock 35amper threw sparks and failed. My servos have at least one of the four small screws in the rear stripped making it impossible as this point to service the damaged gears.
My question is what is the best replacement ESC that I can get, perhaps higher of a 35amp rating, and what are three really good servos that I can get that would be as good if not better than the stock servos.
I was thinking of going to Hobbyking to get this stuff, they seems to have quite a bit of a selection to choose from with some things priced with the economic consumer in mind...any suggestions? What should I look for when shopping for a new ESC and Servo for my blade 4503D?

Personal opinion, here's how I have my 450x set-up and will be setting up my converted 3D.
  • YEP 60 ESC (note, programming card needed as well)
  • Castle CC 10 BEC (castle Link needed if you want to run at 6v) also noteworthy that the built in BEC in the YEPs only run 5.5v
  • KST DS215M servos. Same servos can be run for cyclical and tail (from Helidirect)
  • SK3 Helidrive 3600kv motor (note, 3.17mm shaft size so you'll need a new pinion, stock won't fit)

I'm sure more will chime in, but feel free to fire away with any questions.

I have run the SK3 3600 with stock esc and no CC BEC back to back flights (9/day) with no issues and never any heat issues. I am using the same motor in the 4300 now with a 40amh Kontronik esc.

Yep is ecenomical and a very reasonably priced esc (YGE clone), and is what I use on my X5.

This weekend I will be replacing my cyclic Hitec 5065MG servos with the HK TGY-306G Ultra Fast/High Torque MG Digital Alloy Cased Servo. This ( TGY-211DMH Metal gear Coreless Digital ) is also an equivalent to the plastic case Hitec at an even lower price same spec & double bearing.

Too many issues with the Hitec's and just wanted to try the TGY's for a few reasons. Cost is only a bit more that a gear set for the Hitecs, much faster and can have a complete spare or 2 on hand when needed. No rebuilding or sending them in. They are as fast as my MK95i at the tail at 24% of the cost. Again I can have full spares and save the failed ones for spares. It is worth a try since I have had such good experience with the SK3 drives that require no oiling.

The great thing about the 450 is that you do have several options and most don't break the bank.

Not familiar with any of those.
The YEP is tried and true in these though. If you don't want the 60, you could run the 45 at under $25

Programming card is $6 so for just over $30 you'd be set for a good long time with hardware that's been confirmed to work well in this bird... I know its more than the others, but unless someone else can chime in or you find info somewhere else I'd give it some serious thought..
