The entry level Schroeder model (No.2) has 11 gram effective mass which should work with your 22 compliance Soundsmith Voice according to the calculator on vinylengine.com, which indicated a 5 - 11 gram tonearm effective mass is the range based on the cartridge weight.
If you go to vinylengine.com and search you will see there are a variety of tonearms in that effective mass range; including vintage ADC and SME as well as Moerch, Roksan and many others, some significantly less than $4,000.
The SME III, while too low in mass for most MC cartridges, and out of production, is a precision tonearm available for less than $500, than would work with the Soundsmith Voice cartridge.
If you want the best match, and Soundsmith states that the Schroeder is the best match, that answers your question.
If you want to spend less, there are many options, which are high quality tonearms and available for less money.
