Here is a nice list.
For sizes from DIP (0.1") down to SOIC (0.05") I like the
Tektronix SMG50 ChipKlip or
EZ-Hook XKM type (HP/Agilent shipped the same type with their logic analyzers). Both are regularly available on eBay for something like $1/each. All of the cheaper knock-offs I have tried performed terribly.
For smaller than SOIC things get expensive and fragile fast. The TPI NC1 is the cheapest of the brand-name ones in this category. I do not have experience with the AliExpress grabbers referred to on the Sigrok wiki page.
Most of these grabbers have 0.025" square pins. The best way to attach a scope probe to that is an adapter like
this. These are not universal, so the best way is to buy one made by your probe manufacturer.
Keep in mind that every mm of wire you add degrades performance of your probe (which is why a purpose-made adapter is the best). Every reference you see to keeping the ground lead short and using a low-inductance ground spring for best signal integrity applies equally to extending the probe tip. How much depends on the signal frequency / transition time, and the input capacitance of your probe (lower capacitance means less degradation due to the extra inductance). If your bandwidth needs are very low, you can do the crappy thing of clipping the retractable hook to a piece of wire. When in doubt, put the probe tip directly on the test point to exclude issues caused by the long wires.
