     So roll your own.  (Hints, that is).  Frequency analysis generally
doesn't help much in cyphers this short, but Q is just begging to be
space:

PBEGUUYMI ICUUFGUUYI GUUY CUIVFI GUUY CU BEMEVP 

Which, assuming the plain text is English, makes GUUY on of:

Abba    abbe    Abby    adds    ally    ammo    Anna    Anne
beef    been    beep    beer    bees    beet    book
boom    boon    boor    boos    boot    cook    cool    coon
coop    deem    deep    deer    doom    door    ebbs    eddy
eggs    Ella    Emma    errs    feed    feel    fees    feet
food    fool    foot    good    goof    Haag    Haas    heed
heel    hood    hoof    hook    hoop    hoot    ills    illy
inns    jeep    jeer    keel    keen    keep    leek    leer
lees    look    loom    loon    loop    loot    meek    meet
mood    Moon    Moor    moot    need    nook    noon    odds
offs    Otto    peek    peel    peep    peer    pool    poor 
reed    reef    reel    roof    rook    room    root    seed
seek    seem    seen    seep    seer    sees    soon    soot
teem    teen    took    tool    veer    weed    week    weep
wood    woof    wool    woos    zoom    zoos  
 
...with the caveat that it isn't "peep" (that would make G == Y). 
Noticing that the middle cypher symbol U is also the last in the two
letter cypher word CU and that GUUY occurs inside the two longest
words...

     Well, you get the idea.
