[Amps] Advice on instruments for ham use

[Bill L. Fuqua]

    The 455 (50 MHz) or 465 (100Mhz) are great scopes if they are good condition. They are often available for around $100 or so.  If you have a problem with the attenuator switches perhaps the fix that was recommended earlier will work. 
453 and 454 scopes are good as well. A bit older but good scopes.

My turn with a question. 
What would be a good (cheap) analog  (or digital ) scope to use for the sole purpose of observing my transmitted signal?
And being I have zero experience with a scope, what would be the easiest method of hooking it up? Just a simple loop over the coax or... ?
Something that would fit on (or near) the desk with out taking up the entire desk.
Thanks to all,

  To expound a little further on analog vs digital:

  Analog scopes are fine for a repeating waveform such as RF, or one
  which changes relatively slowly such as an audio frequency voice
  trace.

  Digital scopes are best for a one-time event which is either too fast
  or too slow for the human eye to capture well.  One example would be
  capturing a relay or switch contact bounce.  They also (usually) have
  the ability to store and print out individual traces.

  Each has their place, but for amateur radio purposes, an analog type
  is probably adequate, as well as easier to fix and cheaper to buy.
