Don't have any experience with the Homebrew unit, but since the Choralflange was mentioned, I thought I would throw in my 2 cents.
I have both the Choralflange and the 2010 reissue ADA Flanger. Both are great units in there own right, but IME the Choralflange is much better as a chorus than an flanger. The CF has an analog warmth and an almost subtle tone which is great for the chorus and good if you are looking only for limited flanging.
The ADA is much better for full on, jet swoosh flanging.
I have not checked the pricing recently for used CFs but they held their value well on the used market when they were still in production. I can only guess that the value has risen since they are no longer produced and now may be more expensive than a new ADA 2010 reissue, which seem to be readily available from some online retailers.
I also own the Foxrox TZF and the Chicago Iron flanger, with the TZF edging out all of these as my personal overall favorite, but I would suggest you go for the ADA since it is readily available for a reasonable price.
Please note that the ADA has a fixed power cord rather than a power adapter socket. This could be a big issue to some users depending on pedalboard power convenience and/or using the pedal internationally.
