The #60-1/2 is probably the best design of block plane that Stanley ever came up with, the "Rolls-Royce" of block plane designs - with a decent blade adjuster, adjustable mouth, and it fits in your apron pocket. If going second hand go for an older (pre- 2000s) one with a cast iron skate, (i.e the adjustable section of the sole at the front - the newer ones are mild steel). I carried one in my toolkit for more than 30 years before swapping to a Veritas (megabucks) and it was well used. I'm not sure how good the Faithful reproduction of this is, but probably reasonable based on other Faithful stuff I've seen, although doubtless it will require a bit of fettling to do its' best work. The one thing I dislike is the threaded knob to lock the blade as opposed to the cam/lever arrangement on the original Stanley - I findvit presses onto my palm and makes using the plane foe extended periods less comfortable than it should/could be (I had a Record for a while with this feature - a backward step IMHO). If anyone is interested, you can get a
higher quality blade to fit a (traditional) #60-1/2 plane made by Ray Iles. Record did do a version of this plane, the #060-1/2, but their version is wider and heavier so a lot less handy to use than the original narrow plane I find
The #110 is all very well, but it lacks the adjustable mouth and the blade adjuster of the #60-1/2. It is also NOT a low angle block plane. Unless you are an experienced wooden plane user that lack of blade adjuster can be a problem when it comes to setting the blade really finely. TBH you'd be better off looking for a second hand #60-1/2, or failing that a #9-1/2 (a standard angle block plane, but has a fine blade adjuster and adjustable mouth like a #60-1/2 although a slightly wider blade) or even a #220 (like a #110 - no mouth adjustment, but has a fine blade adjuster). There is also a #120 model - basically a #110 with a lever type blade adjuster, but I'd swerve those and go instead for a #220, as the blade adjuster on the #120 is pretty poor and they can be difficult to set finely
The Rider is probably an out of the box solution (i.e. ready fettled), as opposed to the Faithful which will require half an hour's work to fettle. Personally, given the choice I'd have the Faithful over the Rider, but I'd buy a
Ray Iles O1 iron for it and do the fettling myself. At about £17.50 that blade may cost more than a second hand plane, but is a really good quality blade
When considering the above, please bear in mind that I'm (a) a working chippie and (b) I'm a self-confessed bit of a "tool tart"
