A few years back I started going through Isaiah verse by verse (which I need to get back on). I would read and then write my own commentary, then read other commentaries to make sure I wasn't just reciting what they said; writing what really stuck out. I used Henry, Wesley, Clarke, Scofield, Geneva Bible, and Paul Washer quotes.
After about 3 chapters I pretty much only referenced Scripture and Matthew Henry. Wesley, Scofield, the Geneva Bible, Washer, etc, had something to offer, but didn't comment on the majority of individual verses. So it became tedious and time consuming looking for commentary when it was hit or miss. Henry comments on about 99% of the things said. Occasionally Henry doesn't comment on a verse that stirred my curiosity and I would reference others, but Henry is definitely the best I could find for accuracy and efficiency. Adam Clark was pretty detailed, but he made some comments that just made me shake my head and have to quit referencing him.
I like Missler, too, but he is more for sitting down and listening to topical subjects. I would say Missler hits verses that make you scratch your head better than anyone I have listened to, but hits them here a little, there a little (probably intentionally). Missler lots of times teases a verse and gives you a hint to make you figure it out on your own. He says it will mean more to you if you find it rather than him telling you; always thought this was cool but also wished he would just spill the beans.
Here are some resources that really help me regularly:

http://www.studylight.org/
(the Studylight Parallel Bible search allows you to pull up the early English translations super fast for comparison: Wycliffe, Tyndale, Geneva, etc)
I know you asked for no bias but these help me as well:

Another great resource is opening web pages in Google Chrome, then clicking the wrench on the right hand side and using the "Find" option to look up particular words or phrases. Huge time saver.
I don't see Tyndale's commentary online. Is it available?
