I've personally never seen anything other than pyroban here.
What trouble have you had with pyroban? Personally I've found them nothing but helpful, especially with technical problems.
Think parts are always going to be an issue whatever provider you use due to the 'bespoke' nature of everything. A lot of pyroban parts are standard oem which they modify then send back to you.
