Looking for a Instek GDS-3000 series scope review

[srt8-in-largo]

The waveform update rate is in the manual; max 50,000 Sa/s.

according to the sales rep who emailed the factory, the  refresh rate is 3,000 wfm/s.

Hello again,

Just went to the Agilent Website and the instant quote for the 2000 series is at $1579.00.  That's a bit much for a great scope with only 1 Mpt/channel (Max. optional) wouldn't you think? Also looked at their video...very good attention to details of the video. (NOT done on the cheapo side in other words).

Dave or No Dave i purchased a GDS-3352, the only scope that offers 350MHz 5GSa/s 75ohm, with low ppm under $10Kusd.
The "Low Memory" 25k points and the Medium range wfm/s "85x better than Owon Top of the Line", were enough for me, considering the price i payd, shure, if i had $17.OOOusd. i would have bought LeCroy WaveSurfer 104MXs-B 1GHz 4ch 10GSa/s, 32 Mpts Interleaved, 22.000wfm/s, 10" Touch Screen.
not even a fully maxed out Agilent DSOX3K

problem with Agilent DSOX3K is the 4 GSa/s & the 2MPoints Memory, or 5GSa/s & 4Mpts in the 1GHz version, 2ch $9,965 4ch $13,020usd.
at 5GSa/s anything less than 10MPoints is not enough.
and i hate the software frequency counter.
DSOX3032A similar scope is $6,521usd. 2ch 350MHz 4GSa/s.

i was looking for 5GSa/s minium with as High BW as i could get with as low ppm as my wallet allowed. 

DSOX2022A is limited to 200MHz, and 2GSa/s, with 100 kpts $2,215, yes it has more wfm/s but thats not all.

Tektronix DPO4034B 350 MHz 4-channel Digital Phosphor Oscilloscope is $10,700usd. limited to 2.5GSa/s.
WAVESURFER 42MXS-B $9,990usd.
WAVESURFER 44MXS-B $10,400usd.
less than ideal memory is tolerable, low wfm/s is bad, low BW is worse, and low GSa/s is useless.
in this price range there is always a sacrifice,

for me the Instek GDS-3352 had the balance between the performance vs. price i needed.

shure some people need more the 1M wfm/s of the Agilent 3K for glitch detection,
or the Big memory of the Tektronix DPO4K & Rigol DS4K

Rigol DS4032 $3899usd. is limited to 4GSa/s,
Rigol DS6062 $5600usd, 5GSa/s has 3points at 600MHz, single ch, or 1.5pts both ch, 600ps rise times/200ps per division.
Rigol DS6102 $7500usd, at 5GSa/s has 2 points at 1GHz, single ch, or 1pt both, 400ps rise times.
at that speed 5GSa/s is not enough.

Sounds exciting JuanPC. I wish I could make up my mind!. I don't really need the 5Gsps or I would probably would have bought the scope too.

The DPO performance is weird. The color gradation cannot be set anyhow.
