Default Renix Idle Air Control Valve (IAC Valve)

I am looking for a replacement Idle Air Control Valve for my 1990 6 cylinder Renix motor, as mine intermittently seems to stick, giving a very high idle, I have cleaned mine and shot penatrating oil in it, which temporarlity resolves it, but it started up again giving a very high 2000 rpm idle intermittently, usually on start up.

Anyway I see several brands with a wide range in price.

The Brands I see are....
Crown
Standard Motor Products (SMP)
Wells Vehicle Electronics (WVE)
Replacement
Walker
United Motor Products

These are offered by Rock Auto, or CarParts.Com, or Parts Geek


Are there any brands that are best for Reliability, Quality? Any to avoid?

I want reliability and quality. What have you experienced?

Thanks in Advance.

Looks like Moparpartsgiant has the OEM one in stock.

You can search on the part number to see if there's a cheaper source that's in stock.

$137, ouch. I have not heard of any issues with the aftermarket IACs. It's pretty easy to access and change, and isn't going to strand me like a crank sensor. Save your $100 and order the aftermarket name brand. I'm a cheap SOB so I'd be tempted to try the $10 with free shipping from Amazon.

I'm not convinced the IAC is the cause so I'd go with cheap at this point.
