Hi Shane,
I use Delta servos on the basis of performance and cost.
There are cheaper Chinese made servos, and while I have no doubt they work, they have poor documentation, questionable backup and often no set up and tuning software....not recommended.
Delta is a Taiwanese brand made in China, and DMM is a Canadian brand made in China. Both are good quality, performance and backup and most importantly with good setup and tuning software
at fair prices. To be sure they are more than el-cheapo Chinese, but neither are they eye-watering Yaskawa or Siemens.
750W Delta B2's I buy for $438USD/kit (servo, drive and cables) and are pretty good value for money. 2.4Nm rated and 7.1Nm overload, 3000rpm rated, 5000rpm max.
You might be tempted to go bigger, although I can attest to how damn fast and powerful these 750W units are, but these 1.5kW B2's are 130mm frame for 7.2Nm rated, 21Nm overload
at 2000rpm rated and 3000rpm max for $750USD/kit

These are the 750W units, I've bought ten of them over 3.5 years at this price:
