    Can anyone recommend a good bread board with a lot a features that I
    can get to practice and test circuits? Please e-mail me at
    with any info. Thank You.

    Those solderless breadboards are crap.
    1) Lots of inter-bus coupling capacitance.
    2) Lots of bus inductance.
    3) Worst of all, are the bits of metal (created by insertion/removal of
    part leads) that drop down and eventually cause intermittents and/or
    shorts.
    You are better off doing a "jungle jim" layout than using them.
    Get the prototyping perf boards that have copper pads from Radio
    Shack.
    They have a number of sizes of plain circular pad boards, some with
    power buses for DIP, some that take a DIP and "fan out" the leads to
    multiple pads around the device.
    There are other sources for similar boards, and all of them are far
    superior to the expense and problems that the solderless breadboards
    have.

    The OP wasn't asking for an opinion on breadboards in general, nor on
    whether something "with a lot of features" would be a good choice. I
    think he might be better off with separate power supplies, meters, a sig
    gen, etc. but for someone just starting out the convenience of a single
    "all in one" package may outweigh other factors.
    On the contrary, I've found them to be quite appropriate for one-off
    sim/stim and test setups that can be recycled into the spare parts
    bins afterwards. Yes, due consideration should be made for the
    characteristics of the interconnects, as with any circuit. I must admit,
    though, that I've never experienced the "bits of metal" you describe,
    but then I've never had many metal bits flake off from AWG 24 wire,
    either.
    From the (somewhat sparse) original question I'd guess that the OP is
    looking for something to practice with voltage dividers, 555 timers,
    basic op amps, discrete TTL, and the like. As he has made only one other
    usenet post (under that addy) and included an un-mangled e-mail address
    in both the From line and the body, I suspect that he's a bit new at all
    this and, with some reservations regarding cost-effectiveness, either of
    the two links above would seem to answer his question and to be
    appropriate for his level of expertise.
